Benefits of technology

The patent aims to provide a solution for the issues and difficulties faced by existing polarized prescription eyewear. The technical effect is to overcome the drawbacks associated with the prior art and provide an improved design for polarized prescription eyewear.

Problems solved by technology

Since each of the left and right auxiliary lens elements is detachably attached to the respective one of the left and right lens elements, an air gap is undesirably formed between each of the left and right auxiliary lens elements and the respective one of the left and right lens elements, which can result in undesired internal reflections in the IS conventional eyewear and generation of undesired ghost images or unwanted images.
In addition, the chances of misplacing the left and right auxiliary lens elements after being detached from the left and right lens elements are likely to be high.

Embodiment Construction

[0015]FIGS. 1 to 3 illustrate the preferred embodiment of a polarized prescription eyewear according to the present invention. The polarized prescription eyewear has a three-dimensional viewing function and a blurred vision correction function (such as correcting nearsighted, farsighted and astigmatic vision), and includes an eyeglass frame 2 and left and right lens units 4 that are mounted on the eyeglass frame 2 and that are configured such that left-eye images, which are produced using a 3D display apparatus (not shown) and which are displayed using left-handed circularly polarized light 51, are viewable only by the user's left eye through the left lens unit 4, and right-eye images, which are produced using the 3D display apparatus and which are displayed using right-handed circularly polarized light 52, are viewable only by the user's right eye through the right lens unit 4. Techniques of generating the left-handed and right-handed circularly polarized light 51, 52 for displayin...

Abstract

A polarized prescription eyewear includes: an eyeglass frame; left and right prescription lens elements mounted on the eyeglass frame; left and right UV-cured glue layers; left and right circular polarizers adhesively bonded to the left and right prescription lens elements through the left and right UV-cured glue layers and configured to filter out right-handed and left-handed polarized light, respectively; and left and right hard coating layers formed on the left and right circular polarizers, respectively.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority of Taiwanese application no. 101128029, filed on Aug. 3, 2012.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This invention relates to a polarized prescription eyewear having a three-dimensional viewing function, more particularly to a polarized prescription eyewear including prescription lens elements and circular polarizers bonded respectively to the prescription lens elements.[0004]2. Description of the Related Art[0005]A three dimensional (3D) display apparatus can produce left-eye and right-eye images that are superimposed on a screen for providing a 3D effect. A user can wear a 3D eyewear including left and right lenses that are configured to view the left-eye and right-eye images, respectively, so as to achieve 3D viewing.[0006]U.S. Patent Publication No. 2011 / 0199680 discloses a conventional eyewear having a three dimensional viewing function and including a frame, left and right le...
